Andaman Weather in October: What to Expect and How to Plan
By Andaman Emerald Travels
October is the month the islands change their mind. The first week can feel like the monsoon never left. By the last week, the sea is often settling and the sky is opening up!
I get more questions about this month than any other, because October sits between two seasons and gives no simple answer. That is exactly why it is worth understanding. This guide explains Andaman Weather in October, then turns it into a practical plan: what to pack, how to schedule activities, and when this month can work in your favour. Weather shifts from year to year, so treat the figures below as typical ranges and check forecasts close to departure.

These figures describe the typical pattern of Andaman Weather in October. Local conditions can change quickly, and a bright morning may turn into an afternoon shower.
Why October Is a Transition Month
The southwest monsoon retreats around this time, but the weather doesn’t switch off overnight. Showers remain common, particularly in the first half. The Bay of Bengal can also produce low-pressure systems and storms between October and December, so forecasts matter more than usual.
Here is the good news. As the month moves on, the sky clears, the sea calms and many operators begin restoring regular activity. Prices stay lower than in peak winter, and the islands feel green, quiet and uncrowded. If you are flexible, October can be a smart choice.

The month isn’t one block. I always suggest choosing your dates within it.

Andaman in October: Travel Tips, Weather & more
Here is the practical advice I give every October traveller.
Choose Late October if You Can
Conditions improve noticeably in the final ten days. If your dates are flexible, aim for that window.
Keep Your Plans Flexible
Book refundable or changeable hotels and ferries where possible. A rough sea can postpone a sailing, and flexibility protects your budget.
Schedule Ferries Early in the Day
Morning sailings face less weather disruption than afternoon ones. Never place a ferry on the same day as your return flight.
Keep a Buffer Day
One spare day before departure can save a missed flight. It costs little compared with the stress.
Check Daily Updates
Ask your hotel or operator each morning about ferry and water sport status. Conditions can change within hours.
Protect Your Gear
Use a waterproof phone pouch and a dry bag. Humidity is high, so pack electronics in sealed pouches.
What to Do in October
Some experiences work better than others in changeable weather. Here is how I plan around it.
Good Options on Most Days
Cellular Jail and the light and sound show in Port Blair
Samudrika Naval Maritime Museum
Ross Island, when boats are running
Relaxed beach walks and sunsets between showers
Cafes, local markets and slow island exploration
Better in Late October
Snorkelling at Elephant Beach and North Bay
Scuba diving at Havelock and Neil, subject to operator approval
Sea walks and glass-bottom boat rides
Baratang trips, with a check on road and boat timings
Safety Reminder
If you dive, avoid flying for at least 18 to 24 hours afterwards. Declare any health issues to your instructor, and follow all lifeguard advice.

What to Pack for October
Quick-dry clothes and a light rain jacket
Waterproof sandals and a spare pair of shoes
Dry bag, waterproof phone pouch and power bank
Reef-safe sunscreen, hat and sunglasses
Insect repellent and basic first-aid items
Motion-sickness tablets for ferry rides
Printed copies of ferry and hotel confirmations

Is October Worth It?
It depends on your priorities. If you want guaranteed sunshine and perfect water, choose January or February. If you want value, quiet beaches and green landscapes, and you can stay flexible, late October is worth considering. I would not recommend it for a rigid, tightly packed schedule.
